Surge or intra brake systems on trailers are permitted for those with a gross weight of 15,000 pounds or less primarily due to safety regulations and performance efficiency. These types of braking systems are designed to activate when the trailer pushes against the tow vehicle during deceleration, allowing for a smoother and more controlled stopping experience.

When considering the maximum weight limit for these systems, it reflects the balance between effective braking capability and the potential stress on the braking system components. For trailers heavier than this weight limit, other braking systems (such as electric or air brakes) are required to ensure adequate stopping power and safety on the roads. These systems are generally more effective at higher weights due to the increased dynamics and stopping distance needed to manage heavier loads.

By allowing surge brakes for trailers up to 15,000 pounds, the regulations help maintain safety without compromising performance for smaller loads, while larger trailers need a more robust braking solution to handle the greater demands placed on braking systems during operation.
